 DEPRECATED FUNCTIONALITY

 - List modifications to existing features, where the previous behavior
   wouldn't actually be considered a bug
 
+- MSVC: When trying to find a valid msvc batch file, the existence of the msvc compiler
+  executable is verified for VS6 to VS2015 to avoid executing the msvc batch file when
+  the host/target tool is known not to be present. Always check that the msvc compiler
+  executable is found on the msvc script environment path after running the msvc batch
+  file.  The is predominately needed for recent versions of Visual Studio where the msvc
+  batch file exists but an individual msvc toolset may not support the host/target
+  architecture combination.  For example, when using VS2022 on arm64, the arm64 native
+  tools are only installed for the 14.3x toolsets.

 FIXES
 -----
 
 - List fixes of outright bugs
 
+- MSVC: The installed msvc list is calculated once and cached.  There was an indirect
+  dependency on the target architecture when determining if each version of msvc
+  was installed based on the initial invocation.  It was possible that an msvc instance
+  would not be considered installed due to the tools for the requested target
+  architecture not being installed.  The initial call to construct the installed msvc
+  list now uses an undefined target architecture to evaluate all potential host/target
+  combinations when evaluating if the msvc tools are installed for a given Visual Studio
+  installation.
+- MSVC: Erroneous construction of the installed msvc list (as described above) caused an
+  index error in the msvc support code.  An explicit check was added to prevent indexing
+  into an empty list.
+- MSCommon: Test SConsTests.py would fail when mscommon debugging was enabled via the
+  MSVC_MSCOMMON_DEBUG environment variable.  The mscommon logging filter class registered
+  with the python logging module was refactored to prevent test failure.
+- MSVS: Add arm64 to the MSVS supported architectures list for VS2017 and later to be
+  consistent with the current documentation of MSVS_ARCH.
